T '0 all whom it may concern Be it known that I, CLAYTON F. HOLMES, a citizen of the United States, and a resident of Beaumont, in the county of Jeiferson and State of Texas, haveinvented a new and Improved Smoke-Separatorlkof which the following is a full, 'clear, and exact description.

The object of a new and improved. smoke separator designed for' use in connection with smelter furnaces and other apparatus, and arranged to efi'ectively prevent poisonous or obnoxious gases from passing into the atmosphere, at the same time retaining and saving valuable matter contained in the, smoke.

in order to'accomplish the desired result use is made of a cooling iiume connected at i one end with a source of smoke or gases and at its other end with a suction fan to draw the smoke or gases throughthe coolreceiving receptacles, cooling coils arranged within the cooling flume and connected with a source of cooling medium, and a precipitating tank charged with water or other cooling the said suction fan, said precipitating tank having a jet pipe for supplying the cooling medium to the tan.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in

diat-ely rior to reaching the smoke stack (3 with a cooling Home I) rovidedat its entrance end with a valve which when open disconnects the flame A from the. smoke stack 0 and connects the fiume A with the cooling finme D so that the smoke and aces from the smelter pass into and thron the said cooling fiume D. The fOIWMt contrncted end D of the cooling flume D connects with a suction fan F, of any approved theinvention is to provide. E

medium and into which discharges construction, having a discharge ipe G on the pipe G so that the smoke and gases pass into and through the water contained ing the precipitating tank H.

- Within the cooling flume D are arrangeda series of connected cooling coils Lot which jthe last coil is connected by a pipe I with a }pump or other means for passing water'or ot or cooling medium through the connect- .ed coils I. The first coil I of the series is connected by a pipe I with a boiler or other apparatus for receiving the heated waterin the coils heated by the smoke and gases during their passage through the flume D. {The coils I are arranged transversely to somewhat retard the flow of the smoke and jgases and thus insure an intimate contact of the smoke and ases'with the coils, with l smoke and gases. It will be noticed that the water in the COllS flows in a direction opposite the flow of the smoke and gases so thatthe smoke and gases are graduallyeooled.

The bottom of the flume D is provided with perforations D andupwardly and rearwardly-inclined deflecting plates D adjacent the forward edges of the openings D as plainly indicated in Fig. 2. Immediately below the bottom of the flume D are arranged receptacles J provided with hinged bottoms J for opening the receptacles-periodically with a view to discharge the contents thereof. It is understood that when the hot smoke and gases pass through the flume l) and come in contact with the cooling coils, I then a portion of the smoke and gases is condensed and the solid matter drops through the opening D into the receiving receptacle J in which the soot can uccu'mulate to he eriodicallydischarged therefrom, as previouslv mentioned.

The tank H is supplied with cold water or other cooling medium by a series of annular jet pipes K connected by a pipe K with a pump for suppl. ing the jet pipes K with cold water ore her cooling medium. An overflow pipe L leads from he tank H so as to maintain the water contained therein at a predetermined level, that is, above the perforations in the terminal G of the pipe 6-, so that the smoke and gases must page a view to efiectivelv cool and condense the through the watercontained in the tank H. The bottom of the tank H is connected by a pipeN with a settlin tank 0, and the said pipe N is-provided wit a valve N which is opened from time to timeto discharge the sediment accumulating in the bottom of the tank H. It is understood that the smoke and' gases discharged by the actionof the suction fan F by way of the pipe G into. the

water of the tank H is. deprived'of solid matter which accumulates in the bottom of the tank H. l

- As shownin Figs. 1 and 2, the suctio fan F is located in a building P while the tank H is preferably located adjacent the said building. It is understood that the smoke and gases finally rising out of the open top of the tank H into the atmosphere are free of poisonous or obnoxious matter.

The soot received from the receptacles J and the precipitate accumulating in the tank 0 can be subjected to further treatment for obtaining any valuable matter that may be contained in the soot or precipitates.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A smoke separator for'smelter furnaces and like apparatus, comprising a cooling flume connected at one end with the apparatus, a suction fan connected with the other end of the said cooling flume, a series of connected and vertically extending coolingsuction fan connected with the other end of the said cooling flume, a series of connected and vertically extending cooling coils arranged transversely within the said flume to retard the passage of the smoke and gases through the flume to cool the said smoke and gases, means for delivering water to the coil adjacent to the outlet end of the flume, a

precipitating tank charged with a cooling medium and into which discharges the saidsuction fan, the tank being open at the top,"

and means for delivering a cooling medium in jets in the open top of thesaid precipitating tank.

3. Asm'oke separator for smelter furnaces and like apparatus, comprising a flume leading from the apparatus to a stack, a cooling flume connected at one end with the flume of the apparatus and'provided'at its entrance end with a valve, which when open, closes communication between the stack and. appa ratus, a suction fan connected with-theother end of the said cooling flume, a series of connected and vertically extending cooling -coils arranged transversely within the said flume to retard the passage of the smoke and gases through the flume and'to cool the said smoke and gases, means tor delivering water to the coil adjacent to the outlet end of the flume,-

a precipitating tank charged with'a coolin medium and into which discharges the em suction fan, a'settling tank and a valved connecti'on between the bottom of the said precipitating tank and the said settling tank.

4. ,A' smoke separator for smelter furnaces and like apparatus, comprising a cooling flume connected at one end with theappara tus and provided in its bottom with openings and transversely-extending inclined defleeting plates, soot-receiving receptacles arranged under the said flumes and into which lead the said openings, vertically ext-ending and connected cooling coils arranged transversely within the said 'flume and connected at one end with a source of water supply, a suction .fan connected with the outerend of the said flume, a precipitating tank charged with water, and a discharge pipe leading from the said suction fan and extending into the water contained in the said precipitating tank.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
